T o all 'whom it 'may concern:

Be it known that I, RUDOLF KRAUS, zen of the United York city, Queens, county of Queens, State of N ew York, have invented non' and useful Improvements in `B'Iaonines i'or Coating Walh Paper, ol which the. following; is a specification.

This invention relates to a machine of novel construction for coating `Wall paper with a facing o'r' pulp, and simultanoushr producing en embossed pattern on said lam a citigin the accompanying drawings'. Figure l. is a side elevation of my improved machine', Fig. 2 a plan thereof; Fie'. 2i a vertical soction on line 3'-3, Fig. 2; Fig. l a derail ol the principal rollers; Fig. 5 a face vien' of a piero of Wa l. paper coated by the machine, and Fig. a see-tion on line (SW6, Fw. 5,

.in a frame i() is joni'naled the shalt ll oi' an impression cylinder 'l2 adapted to be rotated from power-shaft i3 by gearing i4, l5. Above cylinder l2 there is secured to frame l() a hopper 16, the lower discharge end oi which extends across such o vlinder. This hopper is adapted to contain a pulp or magma, which, when spread upon the wall paper, is adapted to l'orm a plastic coating` 1 thereon.' Below hopper l is .piurnaled to frame 10, at 17, a distributing or Coating' roller 1S that faces Cylinder l! and receives motionlroni wheel 15 by wheel i9. ,loller i8 is provided with longitudinal peripheral States, residing at New.

grooves which servo to convey a proper quantity of pulp upon the wall paper to be coated' said )a ver or creo passino lrom l KL o deliverv roller 2O between cvlinoer l2 and roller 1S. Book of roller 18 there is arranged, above cylinder 12, a pattern roller l1 journaled in ndjustablr-x bearings This roller also faces of: rotary motion therel'rom by gear wheels l5 and 23. Toc surl'are olI roller 2i is embossed or engraved to prof linder l `ind receives i lue-e anyY suitable pattern r on the coating B, oi' theI wall paper, such for instance as the raised pattern Figs. 5 and 6.

In order to prevent the pulp from clog-ruig roller 21., there is interposed brween the lat! l ter and cylinder 12, the lower run oi an endless cloth 25 that passes over roller Z1 and i also over a. tension roller 26 jeurnaled in ad- `web, a pattern roller bach justable bearings 27 of frame 10. Any pulp which may adhere to this cloth is removed therelron'i by a pair of serapers 28, "2Q, that engage opposii e sides thereof. T he moisture and pulp gathered by the Scrapers drops into n. pan 3i) from which it lon's through pipe 31 into a buche-t 32.

The paper A, delivered from reel 20, first receives its coating 3, of pulp by roller 1S, and then, while thc pulp is still soft, a pattern emlmssed thereon by roller 21. The paper thus eoated and mfnamented is finally dried and painted or \farnished. By my machine ll am enabled to produce. ooated and embossed wall paper having a reiv thin l'acingY ol pulp ,rso that the pliability ol the paper is not objeetionably impaired, while, moreover, its oost of produelion is minimized.

i. A machine oi the eliaraoler deseril ed, comprising an impression cylinder adapted to be engaged by a web, a coating roller adallited to spread a plastic laver upon the web, and a pattern loller bar-l1. ol' the coating roller and ndapted to emboss a pattern upon said laying substantially as speoiliod,

2. llrtmaehine ol the character described, comprising an impression loylinder adapted to lie lengaged by a web, a hopper, a corrul gated coatingroller intermediate hopper and cylinder, and a pattern roller bac/l; of the coating roller, subsdantially as speoilied.

3. ne machine olE tlu` (":iaraol'er described, comprising an impression cylinder adapted to bo engaged by a web, a coatingl roller adapted to spread a plastirI layer upon the ol' the ooatinif rollenl and a cloth between pattern roller and orlinder, substantially as specified.

-i. A marhino ol tho character described,

ycoinprisim 'an impression cylindr-ir adapted to be eng ged by a web. a coating; roller adapted lo spread a plastic layer upon thiA web, a paltorn roller baoli of the :i'ialing roller, a oloth bei Ween pattern roller and cylinder, and Scrapers engaging said cloth, substantially as speoiiied. Y
